Title:
LIGHT SOURCE DEVICE AND PROJECTION TYPE DISPLAY DEVICE
Document Type and Number:
Japanese Patent JP2023072374
Kind Code:
A
Abstract:
To provide a light source device that can prevent an increase in temperature of a wavelength conversion member accommodated in a housing.SOLUTION: A light source device of the present invention has: a wavelength conversion member that converts the wavelength of excitation light; a substrate that holds the wavelength conversion member; an optical member through which the excitation light or light from the wavelength conversion member transmits; a housing that accommodates the wavelength conversion member; an optical holding member that holds the optical member; and a heat conduction member that transfers heat from the wavelength conversion member. The heat conduction member is arranged between the wavelength conversion member or the substrate and the optical holding member.SELECTED DRAWING: Figure 3
